Heat of vaporization has that amount of energy that required to change the state of a substance from liquid to gas.

<u>Explanation:</u>

Enthalpy/heat of vaporization refers to the energy which requires to transform the substance from liquid to gas. The amount of energy and pressure remains same in this process. In constant temperature and pressure, substance can change its form from liquid to gas.

A substance can remain in three forms solid, liquid and gaseous. Energy required to undergo transformation from solid to gas is known as heat of fusion. Latent heat refers to the heat energy to change substance from one state to other.

Answer:

<h2>Angular Displacement 6.28 radians</h2>

Explanation:

for circular motion we are expected to solve for Angular Displacement it is measured in radian

Measurement of Angular Displacement.

we can measure it using the following relation

∅= s/r

where

s = the distance travelled by the body, and

r = radius of the circle along which it is moving.

given that

circumference c, s= 400 m

r= ?

we have to solve for the radius

we know that circumference

$c= 2\pi r$

400= 2*3.142*r

400= 6.282*r

divide both sides by 6.284 we have

400/6.284

r= 63.63 m

Angular displcament

∅= 400/63.63

∅= 6.28 radians
